IMPROVEMENT IN APPARATUS FOR VAPORIZING AND BURNING LlQUlD HYDROCARBONS.

Specification forming part of Letters Patent No. 35,383, dated May 27, 1862.

To aZZ whom it may concern.-

Be it known that I, OSCAR F. MORRILL, a citizen of the United States of America, and a resident of Chelsea, in the county ofSufi'olk and State of Massachusetts, have invented a new and useful improvement in erovapor burners or apparatus for vaporizing a liquid hydrocarbon, mixing the vapors thereof with air, and burning the mixture; and I do hereby declare the same to be fully described in the following specification and represented in the accompanying drawing,which denotes the said invention in longitudinal section.

My erovapor or aerovapor burner is constructed with the fluid-vaporizing conduit arranged to extend across or over the fol-aminous diaphragm or cap of the air and vapor mixing chamber, andfrom thence to pass down and enter the said chamber, as hereinafter described.

nous cap, a, and a chimney, b, the said chamberA being open at its lower end in order that air may have free access to it. Across and over the cap a a tube or conduit, 0, extends horizontally, and thence passes downward alongside of the chamber A, and finally The conduit 0 proceeds from an oil and fluid reservoir, B, which is elevated above the burner in order that a liquid hydrocarbon proceeding from the reservoir may run down through the conduit by the action of gravity, such conduit being provided with a stop-cock, d,by which the discharge of the fluid may be regulated, as circumstances may require.

In the operation of my said apparatus the liquid hydrocarbon, whether it be coal-oil or other inflammable liquid rich in carbon,flows down through the conduit and directly over the foraminous cap a, and consequently when there is a flame onsuch cap the conduit will beheated and the fluid within it will be vaporized, the vapor-being caused to rush into the chamber A and mix with the current of air therein. The intense heat of the flame of the mixture of air and gas will operate to great advantage in heating the conduit and vaporizing the liquid. I have found that with the tube arranged over and across the foraminous cap the vapor is not liable to condense in the chamber A, as it will when produced in a Wick by heat applied to a tube containing such wick. By dispensing with the wick I avoid the charring of it, as well as collecting thereon of gummy or other matters,which operate to clog or injuriously affect its operation.

In the aerovapor apparatus as invented by me, and described and represented in the United States Patents Nos. 18,465 and 20,289, the fluid to be vaporized has to pass through awick and to be raised by capillary attraction. In one of such apparatus it is vaporized by the direct heat of a lamp separate from the burner. In the other apparatus, or that shown in the Patent No. 20,289, the wick-tube or vaporizer is provided with one or more rods or heat-conductors to extend into the chimney and over the foraminous cap of, the mixingchamber.

My improved apparatus avoids the difficulty experienced in those wherein wick or heat-conductors are used, as described. By employing the power of gravity to carry otl' the fluid through the conduit, providing such conduit with a stop-cock and heating the conduit by the flame of the aerovaporburnerap plied directly to the outer surface of the conduit rather than to a conductor or wire extended from the conduit, I can rapidly vaporize the fluid, impart to it a great degree of tension, and so regulate its flowage that there will be no material amount of condensation of it either while in theconduit or after it may have entered the mixing chamber. When condensation of the vapor occurs either in the conduit or mixing-chamber, the fluid is liable to escape from the latter and drop on a table or on whatever the apparatus may be placed. This not only creates a loss of fluid, butis objectionablein various other respects.

I claim- 1. An aerovapor burner as constructed, with the fluid-vaporizing conduit arranged to extend across or over the same and through the chimney, and from thence to pass down alongside of and enter the air and vapor n1ix ing chamber, substantially as described.

2. The combination of the reservoir and its heated or vaporized by the flame of the mixed conduit provided with a regulating or stop air and vapor applied directly to the conduit, cock, as described, with the aerovapor-burner as set forth. in such manner that the fluid to be vaporized shall be caused by the action of gravity to OSCAR MORRILL' pass through the stop-cock and the vaporiz- I Witnesses:
